Aiden is visiting the zoo on a field trip. While at the zoo, he sees a 10 foot tall adult elephant standing next to a 15 foot ta

bogdanovich [222]

Set up a ratio:

10 foot tall elephant / X shadow length = 15 foot tall statue / 18 foot shadow.

Cross multiply:

10 * 18 = X * 15

Simplify:

180 = 15x

Divide both sides by 15:

x = 180 / 15

x = 12

The elephants shadow was 12 feet long.

In AGHI, h = 300 inches, G=30° and H=29º. Find the length of i, to the nearest inch.

dalvyx [7]

Given:

In triangle GHI, h = 300 inches, G=30° and H=29º.

To find:

The length of i.

Solution:

We have, G=30° and H=29º.

Using angle sum property, we get

$m\angle G+m\angle H+m\angle I=180^\circ$

$30^\circ+29^\circ+m\angle I=180^\circ$

$59^\circ+m\angle I=180^\circ$

$m\angle I=180^\circ-59^\circ$

$m\angle I=121^\circ$

According to Law of sines,

$\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}$

Using Law of sines, we get

$\dfrac{h}{\sin H}=\dfrac{i}{\sin I}$

$\dfrac{300}{\sin 29^\circ}=\dfrac{i}{\sin 121^\circ}$

$\dfrac{300}{0.4848}=\dfrac{i}{0.8572}$

Multiply both sides by 0.8572.

$\dfrac{300}{0.4848}\times 0.8572=i$

$530.44554=i$

$i\approx 530$

Therefore, the length of i is about 530 inches.

What is the inverse of the function f(x) = one-ninthx + 2?

Bumek [7]

Answer: 9x - 18

Step-by-step explanation:

Inverse is when you swap the x's and y's and solve for y

$\text{Given: }\quad y=\dfrac{1}{9}x+2\\\\\text{Swapped: }x=\dfrac{1}{9}y+2\\\\.\qquad \quad x-2=\dfrac{1}{9}y\\\\.\qquad 9(x-2)=y\\\\.\quad \large\boxed{9x-18=y}$
